During the last week Chandra completed the observing schedule as
planned.

Real-time procedures were executed on May 26 to patch the
on-board computer flight software to allow simultaneous
commanding of MUPS-A and MUPS-B thrusters for OBC-controlled
momentum unloads. Chandra is now configured to use a mixture of
MUPS-A and MUPS-B thrusters during normal operations. This
improves the reliability of the OBC autonomous safing system.
Real-time procedures were executed on May 26 and 27 to dump OBC-A
and OBC-B memory as a follow-up to the patches. The dumps will be
used to update the baseline memory images maintained on the
ground.

A Chandra press release was issued on May 28 describing results
from a study to better understand the nature of space and time.
Using observations from Chandra, Fermi, and VERITAS of some of
the most distant objects in the Universe, the results set
limits on the quantum nature, or foaminess of space-time at
extremely tiny scales. For details see:

The observing schedule for next week includes an observation of
SNhunt275, which was accepted as a Director's Discretionary Time
Target of Opportunity on May 26. The schedule, with a planned
start of Jun 1, is still in work.
